` Be it known thatI, LARoY LITCFIEED, of

` l Southbridge; in the county of Worcester and State of`Massachusetts,' have invented certain new and useful Improvements 1n`Shuttles for Looms; `and I` do hereby declare that the following is-afull, clear, and exact description of the Same, reference being had to ythe accompanying drawings, forming part of this specification, in which-Figure `1,is allongitudinal section of a shuttle constructed accordingto my invenwhich is coiled the spring which keeps the Spindle 1 lli ypltCe.f t Fig; ,37j is an underside gviewl oftheshuttle.v 1

`2b` 1;" place, which `admits of therepeated raising t and replacing ofthe spindle to renew` the This invention consists in a novel inode ofapplying `a spring to keep the `spindle in yarn, without causingany wearof such a nature as zto throw `the spindleout of place.

` `ais'the spindle and b, thepin which t fastens it in the shuttle,`Thehole which receives the pin b, is placed a little lower than theaxisjof the spindle and the Spindle "is extended some distance behindthe` said 1101. Theparwofthelspindieso extended,

whichulnay be" termed `the heel, is inclined `downward from the pin b inorder to make `room forthe coiledspring d, which holds "the spindle initsplace. `This spring cl, is

f coiled around `aV pinje, `whichvts with a knuckle f,\to the back-partof the spindle.

alittle higher than the `spindle a, and'is compressed `between aShoulder in rearof t the lmuckleand "a suitable bearing in the body Aoftheshuttle. `f Fhepin e, when the spindle is in its` operativeposition as shown in black outline in .Fig.l, stands nearly in t `linewith the spindle, `and the spring d, by

" exertingits forcefabovejthe lpin Z), throws up the heelof` the spindleagainst a bearing `in `thebody of the t shuttle and holds the spindlefirm.` `Thi'sbearing may be formed Win the `body `of the Shuttle, but Iprefer to usethe headofthe regulating screw h, for

which, it receivesthe cop or bobbin.` l When f the Spindlefis inthe lastnamed position the knuckle f stands below, thejpinlb, and holds thespindle against a bearing at t', Ain the upper part of the body of theshuttle.

j, the spring catch which connes the bobbin. This is attached to theheel of the Spindle and thrown ott' the bobbin when the point yof thespindle is raised, by coming in contact with a stationary transversepiny la, placed below and in front of the pin b, and in these respectsresembles the spring of the Shuttlefor which Letters Patent were grantedto` me on the th of September 1851; but the pin c, is so placed that thespring will not, while'` a bobbin is on the spindle, come in contactwith the said pin untilthe point of the spindle is raised some distance,and therefore it will hold equally well a large or small headed bobbinwithout interfering with the firmness of the spindle,

while if a very large headed bobbin be n placed in my other shuttle ittakes oli thev pin k the pressure of the spring'which is necessary tohold the spindle secure. The same difficulty with regard to a largeheaded bobbin is `common to other shuttles.

In this shuttle the firmness of the spindle is in every way providedfor.` The length of the heel c, is such that it prevents lateral play ofthe ypoint of the spindle. The spindle cannot get out of place by wearon the spring which holds it as it will in other shuttles. A new spindlecan be inserted readily and at once adjusted by the regulating screwh.

The shuttle can be as cheaply constructed as my other shuttle or asInostother good shuttles lasthe spindle, or all the rear part "of it andthe pin e, may be vmade of malleable cast "iron, and the spring 7' oflight steel plate riveted to the heel of the spindle.

7 The oop shuttle would `only diiier from` y that represented, in `theabsence of any spring j. What I claim as ymy invention and desire tosecure by Letters Patent, is-

The backward extension of the heel c, ofthe spindle as describedcombined with the application ofthe spring d, above the said heel, andabove and in rearof the pin b,
